Multi-functional doorway exercise device

Abstract

A multi-functional doorway exercise device is an apparatus that safely and securely attaches to a door frame. The apparatus includes a stabilizing bar, a main pullup bar, a first support bar, a second support bar, a left bracket assembly, a right bracket assembly, a left handlebar, and a right handlebar. The stabilizing bar extends across the width of a door frame and locks into the door frame. The main pullup bar, the left handlebar, and the right handlebar allows a user to grasp onto the present invention while performing various exercises with different grip positions. The left bracket assembly and the right bracket assembly attaches the stabilizing bar onto and along both sides of the door frame. The first support bar and the second support bar connect the main pullup bar with the stabilizing bar and allows the main pullup bar to rotate about the stabilizing bar.
